(C is the central atom) True False.Dipole moment = Partial charge on atom * Bond length. Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product ...How many CHLORINE atoms are present in 2.5 micro liters of CHCl3?Please show all steps.
